69. Oh yes the memes indeed.
Consider,
. Let's say
then the problem reduces to
. (Do you understand this step?)
So then replacing a again with our definition we get,
.
0.45 since it’s
0.41 0.42 0.43 0.44 0.45 0.46 0.47 0.48 0.49
A quadratic equation is set up in the form of ax² + bx +c
First set equation = to 0
0= x² - 5x - 24
Next plug into quadratic formula( -b Plus or minus the √b²-4ac) ÷ 2a
[10 plus or minus √(25² - 4×1×24)] ÷ 2
Solve for inner parenthesis first
√625- 96 = √529
Now set up two equations
(10 + √529) ÷2 = x = 16.5
(10 - √529) ÷2 = x = -6.5
So therefore x = 16.5 and -6.5
Answer:
40 minutes
Step-by-step explanation:
Given 1 mile = 8 minutes
5 miles = (5 × 8) minutes
5 miles = 40 minutes
It would take 40 minutes to run 5 miles
